I MAX CRANDALL, OF KINGFISHER, OKLAHOMA, ASS IGNOR OF ONE-HALF TO MARTINJ. MEIER, OF' KING-FISHIEIR, OKLAHOMA.

WINDOW-SCREEN.

To all whom it may concern:

Be it knownthat 1, MAX E. CnA NDALL, citizen of thefU'nited States,resldlng at Kingfisher, in the. county ofKingfisher and State ofOklahoma, haveinvented certain new and'useful Improvements in Window-Screens, of which the following is a specification.

This invention relates to window screens and-has as its object toprovide a novelframe structure for such screens, which frame may bereadily assembled by any one and readily adjusted to fit any size windowwithin reasonable limits.

It is one aim of the invention to so'construct the frame that anyinexperienced person may readily and accurately fit theretothesheet ofscreen material and this without the use of tools.

Varioustypes cf knock down frames have been devised intended to beplaced upon the i the use of such frames,'that the sheet of sheet ofscreen material thereto it may be screen material be accurately measuredand cut or it must be trimmed after it has been tacked to the frame. Ineither event, waste of material is liable to occur and the operation isbothersome. V I mThe present invention. therefore, has as a furtherobject to provide a screen frame of such construction that in applyingthe measured and cut to the width and height of the window opening inwhich the screen is to be arranged and may be readily assembled'with thescreen frame without further measurements being necessary and withoutany particular attention being paid to the stretching of the sheet.

. Another aim of theinvention is to provide a screen frame made upof'metallic rails and stiles, so formed from sheet, metal asSpecification of Letters Patent.

to be rigid in the assembled frame and yet be exceptionally light inweight.

Further the invention has as its object to so construct the stiles andrails of the frame that they may be adjusted as to length and theirsections secured in adjusted position of the completed screen. Fig. 7 isa group perspective view; illustrating one of the rails and one of thestiles in position to be assembled. Fig. Sis a perspective view of oneof the loclnng strips for securing the sections of the stiles and railsat adjustment.

Corresponding and like parts are referred to in the followingdescrlption and indlcated 1n all the views of the accompanying drawingsby the same reference characters.

Except at their ends thestilesand rails of the screen frame are ofcounterpart conprises two telescopically fitted sections which adapt theframe for adiustment as regards its Width and height. Each section ofeach stile and each rail is formed from a sheet metal blank so formed asto be substantially rectangular in cross section. The stiles areindicated in general by the reference character A and the rails by thereference character B, one section of each stile being indicated by thenumeral 1 and the other section by the numeral 2, and one section ofeach rail being indicated-at 3 and the other section at 4. As stated.each section is formed from a sheet metal blank and the blank is sofolded as to provide spaced side portions 5 and 6 and spaced edgeportions 7 and 8. The side portion 5 and edge portion 7 are integrallyconnected by a fold in the blank as also the'side portion 6 and edgeportion 7 and the side portion 5 and edge portion 8.

. struction, and each stile and each rail com- 4, as the case may be,and the free edgepor- The edge portion 8 is provided with a'flange 9which projects inwardly at right angles therefrom and is overlapped bythe free edge of the side portion 6 although spaced therefrom, The saidside portion 6 is folded the said sections differ to such extent as topermit of such fitting. I

When the sections are fitted together, the flange 9 of the section ofsmaller dimensions, which would be the section 1 in the instance of eachstile and the section 3 in the instance of each rail, will be overlappedby the flange 9 of the other section 2 or tion and flange 10 of the sideportion 6 of each of the sections 2 and 4 will be received within thespace between the said portion 6 and flange 10 of each respectivesection1 and 3. For a purpose to be presently explained, each flange 10 is of awidth equal to one-half the width of the section of which it forms apart. The portions 6 of the sections of each stile are cut away, asindicated at 11, at the remote ends of the stile, as are also the edgeportions 8 and flanges 9, sufficient materialbeing left, however, topermit of the edges of the portions 5 and 7 being overturned, asindicated at 12 and 13 respectively so that no sharp edges will bepresented. In a like manner the flanges 10 of the sections of each railare cutaway, as indicated at 14, at the remote ends of the saidsections. The portions 5. of the sections of each stileare provided atthe remote ends of the sections with bolt openings 15, as are also theportions 5 and 6 of the sections of each rail, the latter openings beingindicated by the numeral 16.

In assembling the "stiles and rails, the remote ends of the sections ofeach rail are disposed within the cut away ends of the sections of thestiles and bolts, or other suitable securing elements 17, are fittedthrough the openings 15 and 16 and are provided with nuts 18 which maybe tightened for the purpose of securing the as sembled ends of thestiles and rails to each other. The bolts are not fitted into' place,however, until after the stiles and rails have been connected with thesheet of screen material, as will be presently explained. The sheet ofscreen material is indicated by the numeral 18 and in cutting this sheetfrom the roll it is measured and cut in the same dimensions as thewindow opening in which the screen is to be placed. It is desirable thateach corner of the sheet be cut out, as indicated at 19, by lines ofincisions As stated,

at right angles to each other, so as'to permit of the edge portions ofthe sheet being smoothly fitted to the flanges 10. In fitting the sheetone side edge portion thereof is fitted within the fold forming-theflange 10 of the sections of one of the stiles or rails,

and this member of the frame is turned from v the full line positionshown in Fig. 4 to the dotted line position shown thereln, and

this turning movement is continued until the frame member has assumed aposition the reverse of its full line position, as illustrated at thetop of the said Fig. 4. In thus. rotating the member, the edge portionof the sheet of screen material is folded upon itself over the edge oftheflange 10, in the manner shown at the bottom of the said hooked overthe end edge of the inner sec:

tion of the stile or rail, as the case maybe, with the body portion ofthe strip extending beside the outer face of the portion. 5 of.

the said section. The .sections. are then telescopically fitted one intothe other and after having been adjusted the projectingends of theseveral strips 20 are bent back, as indi-' cated by the numeral 22, soas to engage over the inner end edges of the portions5 of the respectivesections. V

It will now be understood, and particularly by reference to Fig. 3 ofthe drawings,

111g means provided for holding the telethat the locking strips 2'0serve to prevent the sections of the stiles and rails being further slidinto each other after adjust- I ment, and itwill be understood, ofcourse,

that the sheet of screen material 18 serves to prevent the sections ofthe stiles and rails being separated or extended. It will, of course, beunderstood that it is not absolutely essential 'thatthe stiles and railsbe formed in sections telescopically fitted, for

they might be formed in sections adju'stably 7 connected in some othermanner, or they might be formed integral throughout. Nevertheless, theconstruction of the sections adapting them to be telescopically adjustably fitted constitutes an important feature of the invention as doesalso the provision of the flan e 10.

Having t us described the invention, what is claimed as new is:

1. A window screen frame having its members composed of telescopicallyconnected sections, each section being formed from a sheet blank formedto provide spaced side portions and edge portions integrally connectedexcept between one of the side portions and one of the edge portions,the said side portion of each section being provided at its free edgewith a flange for the connection of the edge of a screen sheet.

2. As a new article of manufacture, a window screen frame member formedfrom a sheet blank bent to substantially hollow rectangular form andhaving one side provided with a flange overlapped by the edge portion ofan adjacent side, the said edge portion of the said adjacent side beingprovided with a flange lyin in spaced relation with respect to the saidside and adapted for the engagement therewith of an edge portion of asheet of screen material.

3. As a new article of manufacture, a window screen frame membercomprising telescopically fitted sections, each formed from a sheetblank bent to substantially hollow rectangular form, one side of eachsection being provided with a flange overlapped by the edge portion ofan adjacent side of the section, the said adjacent side being providedwith a flange lying in spaced relation with respect thereto, the saidsections in their assembled relation being arranged with the said edgeportion and the flange of the said adjacent side of one seetion receivedbetween the said adjacent side and the flange of the other section andtelescopically.

4:. A window screen frame comprising separably connected stile and railmembers, each of themembers being formed from a sheet blank bent tosubstantially hollow rectangular form, one of said members having two ofits adjacent walls cut away at its ends, and the members associatedtherewith each having one end disposed within the cut away portion ofthe first-mentioned member, securingelements fitted through theassembled ends of the members, and means upon the members for theconnection of a sheet of screen material.

5. In a window screen, a frame comprising stiles and rails consisting oftelescopically connected sections, and means for holding the sections ofeach stile and each rail at adjustment comprising a strip bent at oneend to engage the interfltted end of one section and at its other endbent to engage with the corresponding end of the other section.

In testimony whereof I aflix my signature in presence of two witnesses.
